That is, He has the power and ability to annihilate completely anyone whom He wills to punish, but it is His mercy that He does not hasten to punish the wrong-doer, but gives him respite for years and centuries to allow him time to think, understand and mend his ways, and is ever ready to forgive the sins of a lifetime if the sinner offers repentance but once.

That is, the seeker after truth does not have to look far for a sign. If only he sees with open eyes the phenomena of vegetation around him, he will be able to judge for himself whether the reality about the system of the world (i.e. Tauhid) which was being presented by the Prophets is true or the speculations of the polytheists and atheists. From the variety and abundance of creation found on the earth, the various elements and factors supporting it, the laws of nature causing it to grow and flourish, and the accord and harmony existing between its characteristics and the countless needs and demands of innumerable creatures, only a fool will conclude that all this is happening automatically without the wisdom, knowledge, power and design of an All-Mighty, All-Powerful Creator. Obviously, many masters and gods could not have by any device arranged and produced the perfect harmony and accord between the soil, the sun and the moon, and the animal and plant life produced with their help and the needs of a great variety of creatures living on the earth. A sensible person, unless he is prejudiced and biased, cannot help feeling convinced that these are the clear signs and proofs of the existence of One God, and there is no further need of a miracle to convince him of the reality of Tauhid.
